The fact that people feel they are not responding to inputs in a deterministic 
way does 
not necessarily mean that it is true. You could put a computer program through 
a TT and 
be completely surprised by its quirky and imaginative responses - then run the 
program a 
second time with the same inputs and get exactly the same responses. There are 
those 
who argue that human cognition is fundamentally different from classical 
computers due 
to quantum randomness, but even if this is the case there is no reason to 
believe that it 
is necessarily the case. Brains would have evolved to give rise to appropriate 
survival-
enhancing behaviour, which precludes random or erratic behaviour. A degree of 
unpredictability would have to be present in order to avoid predators or catch 
prey, but 
unpredictable does not necessarily mean random: it just has to be beyond the 
capabilities 
of the predators or prey to predict. The unpredictability could result from the 
effect of 
classical chaos, or simply from the complexity of the behaviour which is in 
fact perfectly 
deterministic. No true randomness is needed.
